So I was hoping that "Acidified Copper Sulfate" would be as effective as everyone says it is, but I recently had a pigeon with canker that I used it on and it did not make a difference.Perhaps this is just a really stubborn case?

Kathy, look into a product from Medpet called 4 in 1 powder, it was developed for treating pigeons canker, e.coli, paratyphoid, and coccidiosis.
